Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

RECESSED PLATEN

Publishing Venue

Xerox Disclosure Journal

Abstract

When the page of a book is to be copied on a platen-type copier, the standard platen cover is usually in the open position. Consequently, scan-lamp glare is encountered. The standard platen is conventionally positioned in the top surface of the copier and usually occupies the same plane as the top surface of the copier, the latter providing a work area.

RECESSED PLATEN Proposed Eugene P. Ritter Classification

U.S. CI. 355/3 Int. CI. G03g 15/00

When the page of a book is to be copied on a platen-type copier, the standard platen cover is usually in the open position. Consequently, scan-lamp glare is encountered. The standard platen is conventionally positioned in the top surface of the copier and usually occupies the same plane as the top surface of the copier, the latter providing a work area.

In order to obviate the foregoing problem, a recessed platen is provided in a xerographic copier. The transparent support surface forming the platen is positioned below the top surface of the machine and cooperates with an inclined surface which is also recessed to support the part of the book not being copied while a page thereof is being copied.
